Can someone rank my best and undefeated Pokemon team?

Your team isn't bad, and they have a lot of strong moves. However, I really don't reccomend moves that take up a turn. The worst, yet powerful, move would be focus punch. What would happen when Charizard gets hit? That would be a waste. Charizard also knows hyper beam and blast burn. A water Pokemon could be sent out and douse it! Another would be solar beam. A good dark Pokemon could take Deoxys out before it even attacks. Once again, a Pokemon knows hyper beam- Metagross. A steel Pokemon is decently worthless against a water or fire pokemon. That hit could be your last one. Now, something good. The only move I like that take up a turn would be fly, which your salamence knows. I just hate it when I use fly and the opponent uses twister or gust. Be careful about that. Other moves I don't like are ones that have low accuracy. For instance, thunder and fire blast. If they miss, what happens next? A dark Pokemon could take out Mew and an ice Pokemon would take out Salamence. I also believe that dynamic punch is pretty low? Well, just plain old low, actually. It has more of a chance of missing rather than hitting. Now, the last move I'd take out would be Explosion. I mean, come on! I hate explosion! Just tell me why should you have explosion? Just to lose "on purpose"? Yes, it is a strong move. Very strong, in fact, it KO's your own pokemon! Now, one last thing. Don't ever have more than one of the same kind of Pokemon in a team. Don't get me wrong, dude. The Pokemon are good. It's just their moves they know. But, I can tell you that a good team of dark, water, fire, and ice Pokemon could be the first to take out your team. Those are your greatest weaknesses. Be careful about that. I do, though, rate your team a 6/10. Not the best, but not the worst.

I would give it a 7/10 work on your move sets,I could beat your team dude.

Undefeated ?! Go play NetBattle right now !!!
Bad team.

9.5/10

I won't write the whole thing out again. So here's my overall rating for you 10/10 points.

Firstly your team is not the best and secondly Your team will be trashed if you VS me cause my team has more improved and reasonable move sets, unlike yours it needs more work= 7/10 but still pretty good.
